Description

Technical Field

[0001] This invention relates to the field of cylindrical and tapered roller machining technology, specifically to a machining device for cylindrical and tapered roller spherical base surfaces. Background Technology

[0002] Cylindrical rollers are an important functional component of cylindrical roller bearings, and tapered rollers are an important functional component of tapered roller bearings. Both enable relative rotation between the inner and outer rings of the bearing and are widely used in mechanical equipment.

[0003] Machining the spherical base surface of cylindrical and tapered rollers is an indispensable step in the machining process of cylindrical and tapered rollers. Currently, when feeding cylindrical and tapered rollers and then machining their spherical base surfaces, a clamp is needed to hold the cylindrical and tapered rollers and transport them to the grinding mechanism for positioning. After positioning, the clamp is released, releasing the cylindrical and tapered rollers, and then the grinding mechanism grinds the cylindrical and tapered rollers. However, this adds the process of waiting for the clamp to release the rollers, which reduces the working efficiency of grinding cylindrical and tapered rollers. Summary of the Invention

[0004] To address the low efficiency of existing grinding techniques for cylindrical and tapered rollers, this invention provides a device for machining the spherical base surface of cylindrical and tapered rollers. This device features a fixed connection between a pressure plate and a pusher plate, and a rotatable connection between a support plate and the pusher plate. A receiving space for accommodating the cylindrical and tapered rollers is formed between the pressure plate and the support plate. When the cylindrical and tapered rollers reach the machining space, the rotating wheel above moves downwards to press them down, allowing the support plate to rotate downwards and release the rollers. Then, the pressure plate and support plate can be directly removed from the machining space, allowing for direct grinding of the rollers, thus improving work efficiency.

[0005] The technical solution adopted by the present invention to solve the above-mentioned technical problems is as follows: a cylindrical and tapered roller ball base surface processing device, including a device body, a grinding mechanism for grinding cylindrical and tapered rollers, a conveying mechanism for conveying cylindrical and tapered rollers to the grinding mechanism, and a sensing mechanism for sensing the position of cylindrical and tapered rollers and controlling the start of the conveying mechanism.

[0006] The grinding mechanism includes two sets of rotating wheels distributed vertically and a first driver for driving the upper rotating wheel to move vertically. A processing space is formed between the two sets of rotating wheels, and a grinding wheel for grinding cylindrical and conical roller ball base surfaces is arranged on the side of the processing space.

[0007] The conveying mechanism includes a conveying guide rail, a pusher plate slidably disposed on the conveying guide rail, and a second driver for pushing the pusher plate to move. A pressure plate and a bearing plate are arranged sequentially from top to bottom on the side of the pusher plate facing the processing space. The pressure plate is fixedly connected to the pusher plate, and the bearing plate is rotatably connected to the pusher plate. A receiving space for accommodating cylindrical and tapered rollers is formed between the pressure plate and the bearing plate, and the bearing plate can rotate downward to release the cylindrical and tapered rollers.

[0008] As a further optimization of the invention of a cylindrical and tapered roller ball base surface processing device: the pusher plate is rotatably connected to a connecting shell, the connecting shell has a first opening facing the processing space and a second opening facing the conveying guide rail, and the first opening and the second opening are connected in communication; the pressure plate extends through the first opening into the inner side of the connecting shell and is fixedly connected to the output end of the second driver; the bearing plate is integrally connected to the connecting shell; a first spring is provided between the inner wall of the connecting shell and the pressure plate; the first spring is used to pull the bearing plate back to its original position after it rotates.

[0009] As a further optimization of the invention of a cylindrical and tapered roller ball base surface processing device: a limit hook is provided at one end of the pressure plate near the processing space, and a limit protrusion is provided at one end of the bearing plate near the processing space.

[0010] As a further optimization of the invention of a cylindrical and tapered roller ball base surface processing device: the sensing mechanism includes a rotating shaft and a proximity switch, wherein the rotating shaft is fixedly mounted on the device body, and a rotating clamp is rotatably connected to the rotating shaft. A sensing post and a signal rod are spaced apart on the rotating clamp. The proximity switch is used to detect the sensing post. When the cylindrical and tapered roller enters between the pressure plate and the bearing plate, it impacts the signal rod, causing the sensing post on the rotating clamp to rotate, thereby changing the value of the proximity switch. The rotating clamp is connected to the device body through a second spring, and the second spring can drive the rotating clamp to reset.

[0011] As a further optimization of the invention of a cylindrical and tapered roller ball base surface machining device: the grinding mechanism further includes an L-shaped plate, which includes a first part and a second part. The junction of the first part and the second part is rotatably connected to the device body. A limiting member is connected to the part of the first driver that passes through the first part. The back of the limiting member is in contact with the surface of the first part away from the first driver. The rotating wheel located above is rotatably connected to the second part.

[0012] As a further optimization of the invention of a cylindrical and tapered roller ball base surface processing device: the limiting member includes a limiting block, the first part is provided with a through groove, the first driver drives the limiting block through the through groove and then connects two limiting wheels, the limiting wheels are in contact with the surface of the first part away from the first driver.

[0013] As a further optimization of the invention of a cylindrical and tapered roller ball base surface processing device: a connecting rod is provided on the second part, one end of the connecting rod protruding from the second part near the rotating wheel, and the protruding part of the connecting rod is connected to a round hook tension spring. A worm gear seat is also provided at the bottom of the device body, and a spring adjusting rod is provided on the seat of the worm gear seat. A spring pull rod is connected to the top of the spring adjusting rod, and the round hook tension spring is connected to the spring pull rod.

[0014] As a further optimization of the invention of a cylindrical tapered roller ball base surface processing device: the device body is further provided with a positioning shaft located between the two sets of rotating wheels. The positioning shaft is used to position the cylindrical tapered roller by abutting against the recess of the end face of the cylindrical tapered roller when the cylindrical tapered roller enters between the two sets of rotating wheels.

[0015] As a further optimization of the invention of a cylindrical and tapered roller ball base surface processing device: the device body is also provided with a baffle, which can limit the cylindrical and tapered rollers entering the receiving space, and the device body also includes a feeding pipe with the outlet of the feeding pipe facing the receiving space.

[0016] As a further optimization of the invention of a cylindrical and tapered roller ball base surface processing device: the device body is also provided with a connecting plate and a mounting base. The connecting plate is fixedly connected to the pusher plate. The mounting base is used to install a second driver. The output end of the second driver passes through the mounting base and connects to the connecting plate. A limiting rod is provided on both the connecting plate and the mounting base. A protrusion is provided at the end of the limiting rod away from the connecting plate. The diameter of the protrusion is larger than the diameter of the limiting rod.

[0017] Beneficial effects: After the cylindrical and tapered rollers enter the processing space, the upper rotating wheel moves downward to press down on the cylindrical and tapered rollers. The cylindrical and tapered rollers move until they contact the lower rotating wheel. During the movement of the cylindrical and tapered rollers, they push the bearing plate to rotate downward until they separate from the cylindrical and tapered rollers, thereby releasing the cylindrical and tapered rollers. The first driver can directly drive the pusher plate to leave the processing space, that is, the pressure plate and the bearing plate leave the processing space. It is not necessary to use additional robotic arms or other equipment to separate the cylindrical and tapered rollers from the pressure plate and the bearing plate, which improves processing efficiency and reduces the complexity of the device.

[0018] A limit hook is provided at one end of the pressure plate near the processing space, and a limit protrusion is provided at one end of the bearing plate near the processing space. Both the limit hook and the limit protrusion can limit the cylindrical and tapered rollers in the receiving space, preventing the cylindrical and tapered rollers from falling out of the receiving space along the moving direction of the pusher plate.

[0019] When the first driver drives the limiting member to approach the rotating wheel, the first part is released from the control of the limiting member. As the L-shaped plate rotates downward due to its own gravity, the rotating wheel located above, which is rotatably connected to the second part, will also move downward until it contacts the cylindrical and tapered rollers. Then, together with the rotating wheel located below, it drives the cylindrical and tapered rollers to rotate. The travel trajectory of the rotating wheel located above is an arc, which increases the space between the two sets of rotating wheels.

[0020] The circular hook spring is connected to the spring rod. When the grinding ends, the upper rotating wheel returns to its original position, and the circular hook spring is stretched. When the upper rotating wheel moves down again, the stretched circular hook spring can also provide a certain pulling force to compensate for the problem that the upper rotating wheel moves up during the grinding process due to insufficient gravity, which affects the grinding effect.

[0021] The signal rod moves due to the impact of the cylindrical and conical rollers, which in turn drives the rotating clamp connected to the rotating shaft to rotate. This changes the relative distance between the sensing post on the rotating clamp and the proximity switch, thereby changing the value of the proximity switch to determine whether the second driver is working, thus improving the accuracy of the conveying mechanism.

Detailed Implementation

[0028] The technical solution of the present invention will be further described in detail below with reference to specific embodiments. Parts not described or disclosed in detail in the following embodiments of the present invention should be understood as prior art known or should be known by those skilled in the art, such as the model and specific structure of the first cylinder, the model and specific structure of the second cylinder, the internal wiring of the first cylinder, the second cylinder, the sensing mechanism 12 and the controller, and the specific working principle of the proximity switch 122 cooperating with the sensing column.

[0029] Example 1

[0030] A machining device for cylindrical and tapered roller ball base surfaces, such as Figure 1-3As shown, the device includes a main body, on which are mounted a grinding mechanism for grinding cylindrical and tapered rollers 3, a conveying mechanism 2 for transporting the cylindrical and tapered rollers 3 to the grinding mechanism, and a sensing mechanism 12 for sensing the position of the cylindrical and tapered rollers 3 and controlling the start of the conveying mechanism 2. The grinding mechanism includes two sets of rotating wheels 4 distributed vertically and a first driver 11 for driving the upper rotating wheel 4 to move vertically. A machining space is formed between the two sets of rotating wheels 4. A grinding wheel for grinding the spherical base surface of the cylindrical and tapered rollers 3 is arranged on the side of the machining space. To avoid the grinding wheel obscuring other components in the figure, it is omitted from the drawing. The grinding wheel is a conventional technique in the art, and those skilled in the art can combine this invention with conventional grinding wheels. The first driver 11 can specifically be a first cylinder. The conveying mechanism 2 includes a conveying guide rail 203, a pusher plate 201 slidably mounted on the conveying guide rail 203, and a second driver 1 for pushing the pusher plate 201 to move. The second driver 1 can specifically be a second cylinder. A pressure plate 204 and a bearing plate 205 are sequentially arranged from top to bottom on the side of the pusher plate 201 facing the processing space. The pressure plate 204 is fixedly connected to the pusher plate 201 and is positioned on the side of the pusher plate 201 away from the device body. Thus, after the cylindrical and tapered rollers 3 enter the receiving space, the pressure plate 204... Plate 204 and pusher plate 201 not only cooperate to clamp the cylindrical-conical roller 3, but also the pressure plate 204 is relatively closer to the large end face of the conical roller, or closer to the end face of the cylindrical roller away from the device body. This ensures that when the rotating wheel 4 moves downwards, it will not press down on the pressure plate 204. The support plate 205 is rotatably connected to the pusher plate 201, and a receiving space for the cylindrical-conical roller 3 is formed between the pressure plate 204 and the support plate 205. The support plate 205 can rotate downwards to release the cylindrical-conical roller 3. Both the first cylinder and the second cylinder are connected to a controller. The controller controls the operation of the first and second cylinders. The specific connection method between the controller and the first and second cylinders is prior art known to those skilled in the art and will not be described in detail here. After the cylindrical and tapered rollers 3 are conveyed into the receiving space, the second cylinder drives the pusher plate 201 to move along the conveying guide rail 203 until the cylindrical and tapered rollers 3 enter the processing space. After the cylindrical and tapered rollers 3 enter the processing space, the first cylinder drives the upper rotating wheel 4 to move downward and press down on the cylindrical and tapered rollers 3. The cylindrical and tapered rollers 3 move until they contact the lower rotating wheel 4. During the movement of the cylindrical and tapered rollers 3, the bearing plate 205 is pushed downward to rotate until it separates from the cylindrical and tapered rollers 3, thereby releasing the cylindrical and tapered rollers 3. The first driver 11 can directly drive the pusher plate 201 to leave the processing space, that is, the pressure plate 204 and the bearing plate 205 leave the processing space. It is not necessary to use additional robotic arms or other equipment to separate the cylindrical and tapered rollers 3 from the pressure plate 204 and the bearing plate 205, which improves processing efficiency and reduces the complexity of the device. The cylindrical and tapered rollers 3 mentioned in this invention are a general term for both cylindrical rollers and tapered rollers.

[0031] The above are the basic embodiments of the present invention. Further improvements, optimizations, and limitations can be made based on the above to obtain the following embodiments:

[0032] Example 2

[0033] This embodiment is an improvement on embodiment 1. Its main structure is the same as that of embodiment 1, but the improvement lies in: [The following is a more detailed description of the improvement.] Figure 1-3 As shown, the pressure plate 204 and the support plate 205 will be damaged and need to be replaced after long-term use. Direct connection to the second driver 1 makes replacement inconvenient. Therefore, the pusher plate 201 is rotatably connected to the connecting shell 202. The connecting shell 202 has a first opening facing the processing space and a second opening facing the conveying guide rail 203, and the first opening and the second opening are connected. The second opening of the connecting shell 202 facing the conveying guide rail 203 is provided to avoid the support plate 205 being obstructed when rotating, which would affect the working process of grinding the cylindrical and tapered rollers 3. The pressure plate 204 extends through the first opening into the inside of the connecting shell 202 and is fixedly connected to the output end of the second driver 1. The support plate 205 is integrally connected to the connecting shell 202. After the rotating wheel 4 located above presses down on the cylindrical and tapered rollers 3, the support plate 205 will also rotate downward under force. In order to ensure that the support plate 205 can be smoothly reset without affecting subsequent work, a first spring is provided between the inner wall of the connecting shell 202 and the pressure plate 204. The first spring is used to pull the support plate 205 to reset after it rotates. After the cylindrical tapered roller 3 enters the limiting space, when the second driver 1 drives the pusher plate 201 to move towards the processing space, the cylindrical tapered roller 3 will also be subjected to a force towards the processing space. In order to prevent the cylindrical tapered roller 3 from falling out of the receiving space along the moving direction of the pusher plate 201, the pressure plate 204 is provided with a limiting hook 15 near the processing space, and the bearing plate 205 is provided with a limiting protrusion 16 near the processing space. Both the limiting hook 15 and the limiting protrusion 16 can limit the cylindrical tapered roller 3 in the receiving space. After the cylindrical tapered roller 3 enters the receiving space, both the limiting hook 15 and the limiting protrusion 16 are in contact with the surface of the cylindrical tapered roller 3, which prevents the cylindrical tapered roller 3 from falling off during the conveying process. When the cylindrical tapered roller 3 enters the processing space and the rotating wheel 4 above presses down on the cylindrical tapered roller 3 and moves downward, the limiting hook 15 does not contact the cylindrical tapered roller 3. At the same time, since the cylindrical tapered roller 3 will also press down on the bearing plate 205, the limiting protrusion 16 connected to the bearing plate 205 will also move and move to the bottom of the cylindrical tapered roller 3, no longer contacting the cylindrical tapered roller 3. At this time, the cylindrical tapered roller 3 is released.

[0034] Example 3

[0035] This embodiment is an improvement on embodiment 1. Its main structure is the same as that of embodiment 1, but the improvement lies in: [The following is a more detailed description of the improvement.] Figure 3 The sensing mechanism 12 includes a rotating shaft and a proximity switch 122. The rotating shaft is fixedly mounted on the device body, and a rotating clamp 123 is rotatably connected to the rotating shaft. A sensing post and a signal rod 124 are spaced apart on the rotating clamp 123. The proximity switch 122 detects the sensing post. When the cylindrical-conical roller 3 enters between the pressure plate 204 and the support plate 205, it impacts the signal rod 124, causing the sensing post on the rotating clamp 123 to rotate, thus changing the value of the proximity switch 122. The rotating clamp 123 is connected to the device body via a second spring, which can reset the rotating clamp 123. The proximity switch 122 is also connected to the controller and controls whether the second driver 1 operates. The signal rod 124 moves due to the impact of the cylindrical-conical roller 3, causing the rotating clamp 123, which is rotatably connected to the rotating shaft, to rotate. This changes the relative distance between the sensing post on the rotating clamp 123 and the proximity switch 122, thereby changing the value of the proximity switch 122, which determines whether the second driver 1 operates, i.e., whether it drives the pusher plate 201 to move. The proximity switch 122 is mounted on the device body via the switch bracket 121.

[0036] Example 4

[0037] This embodiment is an improvement on embodiment 1. Its main structure is the same as that of embodiment 1, but the improvement lies in: [The following is a more detailed description of the improvement.] Figure 1 and Figure 4As shown, the grinding mechanism has two sets of rotating wheels 4, one set located above the device body and the other set located below. A processing space is formed between the two sets of rotating wheels 4, that is, a certain space must be left to facilitate the entry of cylindrical and conical rollers 3. In order to facilitate the actual working process, the position of the rotating wheel 4 located below does not change, while the rotating wheel 4 located above needs to move up and down. Therefore, the grinding mechanism also includes an L-shaped plate 6. The L-shaped plate 6 includes a first part 601 and a second part 602. The junction of the first part 601 and the second part 602 is rotatably connected to the device body. The first driver 11 passes through the first part 601 and is connected to a limiting member 5. The back of the limiting member 5 is in contact with the surface of the first part 601 away from the first driver 11. The rotating wheel 4 located above is rotatably connected to the second part 602. When the first driver 11 drives the limiting member 5 to approach the rotating wheel 4, the first part 601 is released from the control of the limiting member 5 and rotates downward by its own gravity under the L-shaped plate 6. At this time, the upper rotating wheel 4, which is rotatably connected to the second part 602, also moves downward until it contacts the cylindrical and tapered roller 3. Then, together with the lower rotating wheel 4, it drives the cylindrical and tapered roller to rotate. The grinding wheel processes the spherical base surface of the cylindrical and tapered roller 3. The travel trajectory of the upper rotating wheel 4 is an arc, and the relative position between the two sets of rotating wheels 4 is an oblique line. If the travel trajectory of the upper rotating wheel 4 is a vertical straight line, then the relative position between the two sets of rotating wheels 4 is a vertical straight line. Obviously, the setting of the travel trajectory as an arc increases the space between the two sets of rotating wheels 4, making it easier for the material picking mechanism to remove the ground cylindrical and tapered roller 3. When it is necessary to move the upper rotating wheel 4 upward, the first driver 11 will retract in the opposite direction, moving the limiting member 5 away from the rotating wheel 4 until the back of the limiting member 5 is in contact with the surface of the first part 601 away from the first driver 11. At this time, the L-shaped plate 6 is pulled by the first driver 11 and then returns to its original position.

[0038] Example 5

[0039] This embodiment is an improvement on embodiment 4. Its main structure is the same as that of embodiment 4, but the improvement lies in: [The following is a more detailed description of the improvement.] Figure 1 , Figure 4 and Figure 5 As shown, considering the friction between the limiting member 5 and the first part 601, in order to reduce friction without affecting the function of the limiting member 5, the limiting member 5 includes a limiting block 501. A through groove 603 is provided on the first part 601. After the first driver 11 drives the limiting block 501 through the through groove 603, two limiting wheels 502 are connected. The limiting wheels 502 are in contact with the surface of the first part 601 away from the first driver 11.

[0040] Considering that when the upper rotating wheel 4 moves downward to contact the spherical base surface of the cylindrical-conical roller 3 and then cooperates with another rotating wheel 4 for grinding, the upper rotating wheel 4 may not exert enough pressure on the cylindrical-conical roller 3 due to its own weight alone during the grinding process. This could cause the upper rotating wheel 4 to move upward during the grinding process, affecting the grinding effect. Therefore, a connecting rod 604 is provided on the second part 602. The end of the connecting rod 604 near the rotating wheel 4 extends out of the second part 602, and the extended part of the connecting rod 604 is connected to a circular hook tension spring. 8. The bottom of the device body is also provided with a worm gear seat 7. A spring adjusting rod 702 is provided on the seat body 701 of the worm gear seat 7. A spring pull rod 703 is connected to the top of the spring adjusting rod 702. The round hook spring 8 is connected to the spring pull rod 703. When the grinding ends, the upper rotating wheel 4 is reset, and the round hook spring 8 will be stretched. When the upper rotating wheel 4 moves down again, the stretched round hook spring 8 can also provide a certain pulling force to compensate for the problem that the upper rotating wheel 4 is not heavy enough and moves up during the grinding process, affecting the grinding effect.

[0041] Example 6

[0042] This embodiment is an improvement on embodiment 1. Its main structure is the same as that of embodiment 1, but the improvement lies in: [The following is a more detailed description of the improvement.] Figure 1 and Figure 2 As shown, to prevent the cylindrical tapered roller 3 from falling off during grinding after entering the machining space, a positioning shaft 10 is also provided on the main body of the device, located between the two sets of rotating wheels 4. The positioning shaft 10 is used to position the cylindrical tapered roller 3 by abutting against the recess on the end face of the cylindrical tapered roller 3 when it enters between the two sets of rotating wheels 4. The recess on the end face of the cylindrical tapered roller 3 is a conventional design and a common technical means that those skilled in the art can know, and will not be described in detail here.

[0043] The device body is also equipped with a baffle 13, which can limit the cylindrical and tapered rollers 3 entering the receiving space. The device body also includes a feeding pipe 14, the outlet of which faces the receiving space. When the feeding pipe 14 feeds the cylindrical and tapered rollers 3 into the receiving space, the cylindrical and tapered rollers 3 will move a certain distance toward the device body. To prevent the cylindrical and tapered rollers 3 from falling out of the receiving space during this process, the baffle 13 is provided.

[0044] The device body is also provided with a connecting plate and a mounting base. The connecting plate is fixedly connected to the pusher plate 201. The mounting base is used to install the second driver 1. The output end of the second driver 1 passes through the mounting base and is connected to the connecting plate. A limiting rod 9 is provided on both the connecting plate and the mounting base. A protrusion is provided at the end of the limiting rod 9 away from the connecting plate. The diameter of the protrusion is larger than the diameter of the limiting rod 9.

[0045] The above description of the disclosed embodiments enables those skilled in the art to make or use the invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
